Final answer:
A judge may apply the exclusionary rule to exclude evidence obtained from an illegal search or seizure, in accordance with due process requirements.
Step-by-step explanation:
If law enforcement fails to follow due process when searching a suspect's home, a judge in the suspect's trial may respond by invoking the exclusionary rule. This legal principle prohibits the use of evidence gained from an illegal search or seizure in a criminal trial. Originating from the 1914 case Weeks v. United States and later applied to the states in the 1961 case Mapp v. Ohio, the rule ensures that evidence obtained without a proper search warrant or without fitting the criteria for warrant exceptions, such as consent or exigent circumstances, is not admissible in court. Additionally, the 'fruit of the poisonous tree' doctrine extends the inadmissibility to any further evidence that is derived from the initial illegal search or seizure.
